Magnewin Energy Private Limited is an ISO 9001:2015 Certified and a Custom-built Capacitor manufacturing Company professionally organized. It is managed with long standing experience, profoundly interested in Enhancing Power and possesses an exceptional track record since its inception.
It was started with a humble beginning in the year 1994 at Sangli (Maharashtra) and reached the status of a leading manufacturer of capacitors for variety of applications in power system utilities, industries and research activities.
Over the years 'Magnewin' has developed its own capacitor manufacturing processes using high quality imported raw materials. Tests are carried out rigorously abiding by the National & International Standards. The products have been regularly exported to more than 20 countries.
It retains its position as one of the leading manufacturers of shunt capacitors for power frequency applications in - LV / MV/ HV systems both fixed and automatic switched type and shunt passive tuned/ detuned filters.
'Magnewin' also has been catering to the needs of specially designed water cooled capacitors for industries such as induction heating, melting and hardening applications; custom - built for energy storage, pulse discharge, medical equipment, impulse generators & voltage dividers and so on. 'Magnewin' is a unique enterprise that can address the critical needs of industries and utilities having sophisticated controllers and facing power quality related problems. We have been developing capacitors to meet the stringent requirements under adverse conditions of operation and offering solutions for energy conservation.
Electricity has now been considered as the life line in the rapid growth of any developing country and India is no exception to it considering its march towards becoming a super power in years to come. In current scenario the bridge between generation and demand is widening every day, even though all attempts are made to minimize it. Under the given situation it becomes imperative to use the available power at its highest efficiency and use of capacitors takes the first & foremost step in energy conservation.
“Magnewin” is committed to develop highly reliable capacitors, be it required for electrical utilities / for industry / for defense or for R & D institutions.
“Magnewin” is committed & proud to develop environmental friendly world class technologies / materials and products that save valuable Foreign exchange and make our country self-reliantin its path of progress to become super power. We at “Magnewin” are proud to be shareholders in the National Energy Conservation programme of India.
Magnewin will be known globally as one of the most respected capacitor manufacturing company by 2021.
Training is considered as the most important tool to develop the skills of our both commercial as well as technical staff. Regular Training is imparted by seniors from the company as well as invited guests who are experts in Power capacitor manufacturing.
Plant has a total shop floor area of 22600 sq. feet including world class dust free room of area 3100 sq. feet for manufacturing all the types of capacitors. Separate store ( clean air conditioned ) is used for Class "A" raw materials like film, foil and insulating materials. Another store for rest of the materials is maintained. All the materials are carefully handled using latest material handling equipment. The plant consists of necessary machinery for winding the elements, their testing and assembly for the capacitors. The plant also consists of the latest facilities for carrying out the routine and type tests as per national and international standards. The special application capacitors are also tested according to the prescribed specifications by the customer.
All the major raw materials like double hazy film , Al foil and NPCB oil are all imported from the reputed manufacturers from Japan, France, Korea and USA .
Capacitor manufacturing starts in specially fabricated clean rooms in line with international clean room standards. The complete manufacturing and operations starting from winding till insertion of dry packs into the container and top lid welding are carried out in a class 10000 zone and element winding is carried in class 100 zone on four semi-automatic precision winding machines. Aluminum foil, which acts as electrode has its end and edges folded during winding of the element. Element winding is done as per the data from the design software, wound elements are tested and healthy elements are stacked to achieve the desired capacitance and voltage to form a dry pack. Soldering and electrical connections are carried out to achive the desired mfd and voltage rating of the dry pack. After wards the pack is wrapped with several layers of high grade insulation paper and is then inserted into pre-treated, degreased sheet metal containers and top lid welded with TIG welding. Porcelain bushings of adequate BIL are TIG welded on the top lid.
The operations & moment of dry capacitors from winding stage till pack insertion into the containers is done on specially designed motorized conveyors.
The impregnated capacitors are sealed and subjected to all routine tests as per IEC 60871-1 and then subjected to 20% A C overvoltage test for a pre-determined period as per company standards. All the passed capacitors are grit blasted, followed by air drying epoxy paint.
Research & Development is a continuous on going activity being carried out to enhance the reliability & life of capacitors and adopting cost reduction techniques by improving and adopting new manufacturing techniques, automation, installing precision on line instruments to monitor the behavior of capacitors during process etc. Formulating new rigorous in-house test standards to asses' life expectancy and behavior of capacitors under extreme operating & environmental conditions. Developing capacitors with new dielectrics is also one of key area of R & D.
Our engineers have also been working on developing dielectric materials and impregnants for use in special application capacitors for making high energy density capacitors in compact Size. Today Magnewin is proud to be the only company in India to manufacture such a wide range of capacitors, which has been possible on account of its innovative strong technical base, R & D and the passion of the management to keep research and development as an ongoing process.
"All Magnewin brand capacitors comply to reputed International standards like..IEC,BS,VDI,IEEE,BIS,JIS and ANSI etc".
